    Global Coatings Network News:

    Scientists from the Brookhaven National Laboratory of the U.
    Department of Energy (DOE) announced on August 1 that in collaboration with researchers from the University of Seville (Spain) and the Central University of Venezuela, they have discovered a new method that can convert CO2 into methanol.
    Highly active catalytic system-copper-cerium interface combination.
    The new catalyst system converts CO2 into
    methanol 1000 times faster than pure copper particles, and nearly 90 times faster than common copper/zinc oxide catalysts currently used in industry.

    The activation of CO2 and its hydrogenation to alcohols or other hydrocarbon compounds is an important way to recycle CO2.
    But this is a challenging task because of the difficulties associated with the chemical inertness of carbon dioxide.
    The catalytic activity of pure metal and bimetal systems generally used for CO2 chemical activation is low, while the activity of the new catalytic system is significantly higher than other currently used catalysts.
    Global Paint Network understands that recent studies have determined that CO2 activation and methanol synthesis can rely on the active centers of Cu/ZnO/Al2O3 industrial catalysts.
    The interaction of copper with CO2 alone is very poor, and it must be alloyed with zinc to make the reaction into methanol better and faster.

    The joint research team gave a completely different type of experimental and theoretical basis for CO2 activation this time: This is the copper-cerium interface, which is highly active for methanol synthesis.
    The combination of metal and oxide centers at the copper-cerium interface provides a favorable reaction path for the conversion of CO2 to methanol, rather than relying on Cu-Zn alloys.
    The joint research team explored a catalyst composed of copper and ceria nanoparticles, sometimes mixed with titanium dioxide.

    These studies have shown that the metal component of the catalyst alone cannot perform all the chemical steps necessary for methanol production.
    The most effective binding and activation of CO2 occurs at the interface between metal and oxide nanoparticles in the cerium oxide/copper catalytic system.
    The researchers pointed out that the key active center for this chemical transformation involves atoms from the copper and oxide phases.

    The researchers believe that their research shows that methanol synthesis can be obtained by appropriately adjusting the properties of the metal-oxide interface in the catalyst.
    This is a very interesting step, creating a new strategy for the design of active catalysts for the synthesis of alcohols and related molecules.
